Ghost Kitchens & Commissaries: Buildout Requirements and Costs (2026)

Ghost kitchen vs. commissary vs. shared kitchen

Three models get conflated. A ghost kitchen is your own permitted commercial kitchen, built for delivery and pickup with no dining room — your lease, your equipment, your health permit. A commissary is an established permitted kitchen that rents production time and storage to food businesses (caterers, food trucks, delivery brands) — you operate under its infrastructure. A shared or incubator kitchen is the commissary model with more services: hourly rates, cold storage, sometimes packaging and permit hand-holding.

The decision is capital versus control. Commissary and shared-kitchen access in the Bay Area runs roughly $25–$45+ per hour or negotiated monthly rates — no buildout, fast start, but you're scheduling around other tenants. A ghost kitchen buildout is six figures but the kitchen is yours at 2 a.m. on a Friday.

What you skip without a dining room

• Dining-room finishes, furniture, and decor — typically $50K–$150K of a full restaurant budget
• Most customer-facing scope: waiting areas, host stations, extensive customer restrooms (verify local code — employee facilities and an accessible path are still required)
• Lower occupant loads — simpler exiting and often a lighter ADA scope than a 60-seat dining room
• Premium storefront rent — ghost kitchens live happily in industrial and back-of-center spaces where rents run far below retail corridors
• What you still need: a compliant pickup/driver flow, signage that couriers can find, and parking or loading that doesn't enrage the landlord

Health permitting doesn't shrink

The county reviews a delivery-only kitchen exactly as hard as a dine-in kitchen, because the food-safety scope is identical. Expect the full stack: Type I hood and suppression over grease-producing equipment, a grease interceptor sized to your menu, the complete sink package (three-compartment, prep, hand, mop), washable finishes with coving, and County of Santa Clara Environmental Health plan check before construction plus inspection before opening.

One extra check that surprises operators: zoning. Some cities treat a delivery-only kitchen as light industrial or catering use rather than a restaurant, which changes which spaces you can legally lease. Verify the use classification before signing — it's the same before-the-lease discipline as any restaurant deal.

Cost per square foot reality

Plan on $100–$250 per square foot for the buildout depending on what the space already has — the low end assumes existing hood and grease infrastructure, the high end assumes converting raw space. Ghost kitchens run small, typically 800–1,500 sq ft, so all-in projects commonly land between $150K and $400K including equipment ($50K–$150K of that). Compare a typical 2,500 sq ft dine-in buildout at $600K–$1.1M and the appeal is obvious: you're buying only the part of the restaurant that makes food.

When a ghost kitchen graduates to a dining room

Adding seats later is a real construction event: occupancy reclassification, restroom counts driven by occupant load, ADA dining and path-of-travel scope, possibly parking requirements — not just tables in the front. If a dining room is plausibly in your future, choose the first space with that in mind (occupancy headroom, restroom plumbing capacity, a front that can become an entrance) or accept that the ghost kitchen stays a production facility and the eventual dining room opens as a second location. We model both paths in the pre-lease site review so the choice is a number, not a hope.
